DUAL SD card mod, connecting two SD cards at the same time - Windows Mobile Development and Hacking General

As the title says, I'd like to connect to memory SD cards at the same time to the device.
I've read spec pages, and it seems the device supports two SD's at once (moreover, the SANDISK wifi+memory SD wouldnt work otherwise).
However, I'm not sure how WM OS supports two memory cards at once. how do the cards mount (how does it work on the dell x50 which has both sd and CF for example) one card mounts to /storage card , and the other ?
also, any ideas about the pinouts ? an SD card/SDIO have 9 pins, but if I'd like to connect more then one, do I connect both to the same pins ?

The biggest SD card available is only 2gb and most brands work without problems. I personally have used only SanDisk (standard model), no point of using the Ultra II or III models since there is no speed improvement and costs a lot more. Some users have tried 4gb RS MMC but there were too many mixed reactions here. I suggest you do a search as there are threads regarding this topic.
All SD cards I bought worked straight out of the box. There are instances that a card fis not recognized by the device if it was formatted from a PC using a card reader. Most of the time the problem lies in the card reader. There is also a possibility of formatting the SD card from the Magician.

Are you sure the card can be detected properly? do you have a sd card reader to see if windows can detect?
I don't have SD reader
No, i don't have a sd card reader to use with the computer to verify the card, but the sd card is a Kingstom standard mini sd card with him adapter to SD.
The card isn't reconigzed by the prophet and isn't reconigzed by the magician.
The type and size have problems with this models of XDA?
My guess is that the mini-sd to sd card adapter is busted. you should double check with another device to be sure. I doubt sd slot on the pda is busted (have you tried another sd card?). I've used a 2gig sandisk mini-sd car with an adapter in my dopod818pro no problems.
my miniSD adapter is a bit.. wacky. Try this.
Take both of them out.
Take the miniSD out of the adapter
Reinsert it, firmly but not too 'pushy'.
Now, the trick here, when you insert both of then into your phone, try not to push it on the miniSD, instead, push it on both side of the adaptor (eg ONLY touch the adapter when pushing into the phone, and balance it (left and right)).

Sandisk 4Gb read-only on PC

I recently purchased a Sandisk 4Gb microsd card for use with the Tytn II. The card works correctly on the Tytn. I wanted to transfer a large file to the card by means of the card reader sddr-113 that came with the card. I plugged the microsd card into the sd adapter, put the latter into the card reader, and plugged the card reader into the usb port of the PC.
On trying to write the file to the card an error message popped up saying the card was read-only. I double-checked that the read-only tab on the sd adapter was in the correct position to enable writing but the error persisted. I formatted the card on the Tytn but to no avail. Sandisk support does not list any known issues.
Knowing that several users have purchased a similar card for the Tytn II, has anyone encountered such problems, and is there any fix/workaround? Thanks.
EDIT: Note that there is no problem reading files from the card on the PC. Transfer speed in this case seems quite good. MY PC is WinXP.
You might check the microSD adapter. The adapters that are a std sized SD card have the small "read only" switch on the side of the card, you may have bumped it. Mine isn't even labeled, it should be switched forward, towards the gold contacts.
Good luck.

As I said, I checked that the read-only switch was in the right position. That said the adapter may be defective, and I'll try to put the microSd into another adapter. However any news from others with possible the same problem will serve to see if mine is an isolated case or not.
Oops, sorry, yup I'd try a different adapter, they're pretty cheap/fragile. I have only seen this once, on a friends card. The tip is that the native microSd card is writeable in another device so it really points to the adapter.
I am also experiencing this issue with the exact same card & adapter.
GRRR it really take age to copy data across active sync...

I had this problem as well. I later found that my PC wanted me to format the card when reading it with the adapter. Luckily my card didn't have anything important on it at the time. When I pulled the card to use it in my Tilt, the new device couldn't read it either.
I was able to use the card & adapter with a program found in a post on this forum to repair my corrupted card.

Mini Sd card not recognized in my wizard

hi guys your forum is great cant stop reading.But i have an issue i recently bought an 4gb mini sd card for my phone the card works but is like it works when it feels like if i put it in and wait for a while or just randomly turn the phone off and on it will work i format it using my card reader through windows on fat32 and all the thing is it works but i should not have to be going through all of this for the sd card to work.
My next problem is i recently upgraded to SNN Edition Version 3.0 LITE and i have to say i love it but before my phone could detect my sd card and from i did i upgrade its not detecting my card at all to be on the safe side i took out the card before the upgrade and now its not detceting at all please can any one help me is there a patch i can use or something HELP!!
i think try to format via fat16 option. i had earlier 2gb kingston card sdmini after formatting it works welll
i was doing some reading and i was told that 2gb is the highest for formating with fat16 i have a 4gb card so this cant work for me a even look in properties and the only option is fat32.any body else as any more in puts.
4GB cards are almost exclusively multilayer, and cannot be read by the Wizard's card reader. You are basically limited to 2GB, and it should be formatted as FAT, not FAT32, as was already noted. If there's a 4GB model that's single layer, that's great, but I don't know about it. (...not saying I'm the definitive authority, either...)
which program can i use in windows to format the card in FAT and not FAT32 and as i said before the phone could read the card before i did the upgrade the only thing its takes a while for the phone too detect the SD card and thats in FAT32 format but i will try the FAT format.
from my experience you can't put ANY 4gb minisd card into the wizard and have it work correctly since it uses double buffering which the wizard doesn't support.
you have 2 options.. either buy a 2gb one.. or format only half of the card in FAT ...as myrddin said.. this might use only 1 buffer..
if that doesn't work, you can look for a program which blocks clusters and block half of the clusters on the card. that would certainly work but you won't be able to get 4gb out of that card ever again.
i'd go with the first option.. 2gb cards aren't that expensive nowadays.
well guys i bought the sd card for my phone and i research before buying it and it caused work so there must be a way for this to work even if i have to split it in 2 partitions but i am at work now so when i get home i will work on it (good thing i bought that card reader) lol but i will give you guys an update soon i plan to format the card in fat16 all 4gb if that dont work i am going to split the partition in 2 but i would love a single partition but what ever works.
I have a 2gb SD Card...
Hey guys... i have a 2gb kingston card (micro SD with adaptor to miniSD), but i have the exact same problem... my wizard just stopped reading the card!

Correct-o-mundo.
Another common problem (related more to card readers than just to Wizards) is that the reader contacts (and even the card contacts) can become worn, dirty, or corroded. Try removing the card and battery, and get in there with a VERY bright light, a magnifying glass, and some cotton swabs dipped in isopropyl. Clean the metal contacts on both card and Wizard. Be careful not to soak the chip. Damp, not wet. Soak the chip and you WILL be buying a new one soon.
Let things dry COMPLETELY before trying anything, or you'll be sorry.
